A female bottlenose dolphin spent six days carrying her dead newborn calf on her back to prevent it from sinking [1].
The footage, recorded by researchers from Geographe Marine Research, provides a rare glimpse into the grieving behaviors of marine mammals. Such observations help scientists understand the emotional and social complexities of cetaceans in the wild.
The dolphin, identified by researchers as Fraggle [2], was filmed off the coast of Western Australia near Geographe Bay [3]. The video shows the mother keeping the calf near the surface of the Indian Ocean, resisting the natural pull of the current that would take the body to the seafloor [3].
Researchers said the mother dolphin continued this behavior over a period of six days [1]. This specific action, carrying a deceased offspring to keep it afloat, is a behavior observed by researchers in other instances of dolphin motherhood [4].
The footage was originally captured and shared in early 2024 [1], [3]. It highlights the intense bond between a mother and her calf, even after death has occurred. The persistence of Fraggle's efforts indicates a strong maternal instinct that overrides the biological reality of the calf's condition.
While the event is heartbreaking, it serves as a critical data point for marine biologists studying the cognitive abilities of bottlenose dolphins. The ability to recognize death and attempt to preserve the body suggests a level of awareness, and emotional processing, similar to other highly intelligent mammals.
“A female bottlenose dolphin spent six days carrying her dead newborn calf on her back.”
This behavior underscores the complex emotional lives of dolphins, suggesting that maternal bonds persist beyond the death of the offspring. By documenting these events, researchers can better categorize the mourning rituals of marine mammals, which may influence conservation efforts and the understanding of cetacean intelligence.
